TROUBLESHOOTING ACCELERATOR SYSTEM FOR IMPLANTABLE DRUG DELIVERY PUMPS
First Claim
1. An implantable drug pump, comprising:
- a plurality of reservoirs selectively rotatably disposed within a housing such that any one of the plurality of reservoirs can be positioned to be in fluid communication with an outlet port formed in the housing, and any one of the plurality of reservoirs can be positioned to be in fluid communication with an inlet port formed in the housing;
at least one valve disposed between the plurality of reservoirs and the outlet port, the at least one valve being effective to control the flow of fluid from the plurality of reservoirs to the outlet port; and
a driver mechanism effective to selectively drive fluid from the plurality of reservoirs to the outlet port.

Abstract
An implantable pump and methods for detecting leaks in an implantable pump are provided. In one embodiment, the implantable drug pump includes a housing having at least one inlet port and an outlet port formed therein. The outlet port is adapted to communicate with a catheter for delivering fluid to a patient'"'"'s body, and the inlet port(s) are effective to deliver fluid into the housing. The housing further includes at least one reservoir disposed therein and effective to contain a fluid. In use, the pump preferably includes a fluid having one or more drugs disposed in at least one of the reservoirs, and a radiolucent fluid disposed in one of the reservoirs. A user programmable control mechanism is coupled to the drug pump and is effective to selectively control movement of the valves between the open and closed positions.
